2015 MAZDA MODEL CX-9 warning light

Black plate (207,1)
Tire Pressure Monitoring Systemí
The tire pressure monitoring system (TPMS) monitors the pressure for each tire.
If tire pressure is too low in one or more tires, the system will inform the driver via the
warning light in the instrument panel and by the warning beep sound.
The tire pressure sensors installed on each wheel send tire pressure data by radio signal to
the receiver unit in the vehicle.
Tire pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tire temperatures are also lower.
When the tire temperature decreases, the air pressure decreases as well. The TPMS warning light
may illuminate more frequently. Visually inspect the tires daily before driving, and check tire
pressures monthly with a tire pressure gauge. When checking tire pressures, use of a digital tire
pressure gauge is recommended.
TPMS does not alleviate your need to check the pressure and condition of all four tires
regularly.

qTire Pressure Monitoring System
Warning Light
This warning light illuminates for a few
seconds when the ignition is switched
ON.
Thereafter, the warning light illuminates
and a beep is heard when tire pressure is
too low in one or more tires, and flashes
when there is a system malfunction.
WARNING
If the tire pressure monitoring system
warning light illuminates or flashes, or
the tire pressure warning beep sound is
heard, decrease vehicle speed
immediately and avoid sudden
maneuvering and braking:
If the tire pressure monitoring system
warning light illuminates or flashes,
or the tire pressure warning beep
sound is heard, it is dangerous to
drive the vehicle at high speeds, or
perform sudden maneuvering or
braking. Vehicle drivability could
worsen and result in an accident.
To determine if you have a slow leak
or a flat, pull over to a safe position
where you can check the visual
condition of the tire and determine if
you have enough air to proceed to a
place where air may be added and
the system monitored again by an
Authorized Mazda Dealer or a tire
repair station.
Do not ignore the TPMS Warning Light: Ignoring the TPMS warning light is
dangerous, even if you know why it is
illuminated. Have the problem taken
care of as soon as possible before it
develops into a more serious
situation that could lead to tire
failure and a dangerous accident.
Warning light illuminates/Warning
beep sounds
When the warning light illuminates, and
the warning beep sound is heard (about 3
seconds), tire pressure is too low in one or
more tires.

Adjust the tire pressure to the correct tire
pressure. Refer to the specification charts
(page 10-7).
CAUTION
When replacing/repairing the tires or
wheels or both, have the work done
by an Authorized Mazda Dealer, or
the tire pressure sensors may be
damaged.NOTE
lPerform tire pressure adjustment when the
tires are cold. Tire pressure will vary
according to the tire temperature, therefore
let the vehicle stand for 1 hour or only drive
it 1.6 km (1 mile) or less before adjusting
the tire pressures. When pressure is
adjusted on hot tires to the cold inflation
pressure, the TPMS warning light/beep may
turn on after the tires cool and pressure
drops below specification.
Also, an illuminated TPMS warning light,
resulting from the tire air pressure dropping
due to cold ambient temperature, may turn
off if the ambient temperature rises. In this
case, it will also be necessary to adjust the
tire air pressures. If the TPMS warning
light illuminates due to a drop in tire air
pressure, make sure to check and adjust the
tire air pressures.
lAfter adjusting the tire air pressures, it may
require some time for the TPMS warning
light to turn off. If the TPMS warning light
remains illuminated, drive the vehicle at a
speed of at least 25 km/h (16 mph) for 10
minutes, and then verify that it turns off.
lTires lose air naturally over time and the
TPMS cannot tell if the tires are getting too
soft over time or you have a flat. However,
when you find one low tire in a set of four-
that is an indication of trouble; you should
have someone drive the vehicle slowly
forward so you can inspect any low tire for
cuts and any metal objects sticking through
tread or sidewall. Put a few drops of water
in the valve stem to see if it bubbles
indicating a bad valve. Leaks need to be
addressed by more than simply refilling the
trouble tire as leaks are dangerous - take it
to an Authorized Mazda Dealer which has
all the equipment to fix tires, TPMS systems
and order the best replacement tire for your
vehicle.

If the warning light illuminates again even
after the tire pressures are adjusted, there
may be a tire puncture. Replace the
punctured tire with the temporary spare
tire (page 7-8).
NOTE
A tire pressure sensor is not installed to the
temporary spare tire. The warning light will
flash continuously while the temporary spare
tire is being used.
Warning light flashes
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
qSystem Error Activation
When the TPMS warning light flashes,
there may be a system malfunction.
Consult an Authorized Mazda Dealer.
A system error activation may occur in
the following cases:
lWhen there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
lWhen using the following devices in
the vehicle that may cause radio
interference with the receiver unit.
lA digital device such as a personal
computer.
lA current converter device such as a
DC-AC converter.
lWhen excess snow or ice adheres to
the vehicle, especially around the
wheels.
lWhen the tire pressure sensor batteries
are exhausted.
lWhen using a wheel with no tire
pressure sensor installed.
lWhen using tires with steel wire
reinforcement in the side walls.
lWhen using tire chains.
qTires and Wheels
CAUTION
When inspecting or adjusting the tire
air pressures, do not apply excessive
force to the stem part of the wheel
unit. The stem part could be
damaged.
Changing tires and wheels
The following procedure allows the
TPMS to recognize a tire pressure sensor's
unique ID signal code whenever tires or
wheels are changed, such as changing to
and from winter tires.
NOTE
Each tire pressure sensor has a unique ID
signal code. The signal code must be
registered with the TPMS before it can work.
The easiest way to do it is to have an
Authorized Mazda Dealer change your tire and
complete ID signal code registration.
When having tires changed at an
Authorized Mazda Dealer
When an Authorized Mazda Dealer
changes your vehicle's tires, they will
complete the tire pressure sensor ID signal
code registration.
When changing tires yourself
If you or someone else changes tires, you
or someone else can also undertake the
steps for the TPMS to complete the ID
signal code registration.
1. After tires have been changed, switch
the ignition ON, then back to ACC or
OFF.
2. Wait for about 15 minutes.

3. After about 15 minutes, drive thevehicle at a speed of at least 25 km/h
(16 mph) for 10 minutes and the tire
pressure sensor ID signal code will be
registered automatically.
NOTE
If the vehicle is driven within about 15 minutes
of changing tires, the tire pressure monitoring
system warning light will flash because the
sensor ID signal code would not have been
registered. If this happens, park the vehicle for
about 15 minutes, after which the sensor ID
signal code will register upon driving the
vehicle for 10 minutes.
Replacing tires and wheels
CAUTION
Ø When replacing/repairing the tires
or wheels or both, have the work
done by an Authorized Mazda
Dealer, or the tire pressure sensors
may be damaged.
Ø The wheels equipped on your
Mazda are specially designed for
installation of the tire pressure
sensors. Do not use non-genuine
wheels, otherwise it may not be
possible to install the tire pressure
sensors.
Be sure to have the tire pressure sensors
installed whenever tires or wheels are
replaced.
When having a tire or wheel or both
replaced, the following types of tire
pressure sensor installations are possible.
lThe tire pressure sensor is removed
from the old wheel and installed to the
new one.
lThe same tire pressure sensor is used
with the same wheel. Only the tire is
replaced.
lA new tire pressure sensor is installed
to a new wheel.
NOTE
lThe tire pressure sensor ID signal code
must be registered when a new tire pressure
sensor is purchased. For purchase of a tire
pressure sensor and registration of the tire
pressure sensor ID signal code, consult an
Authorized Mazda Dealer.
lWhen reinstalling a previously removed tire
pressure sensor to a wheel, replace the
grommet (seal between valve body/sensor
and wheel) for the tire pressure sensor.

NOTElThe detectability of the radar sensors has its limitations. The Blind Spot Monitoring (BSM) System
may not operate properly under the following conditions:
lIce, snow, or soil adheres to the rear bumper surface around the radar sensors.lDuring adverse weather conditions such as rain or snow, or under conditions where water is
sprayed.
lThe rear bumper area around the radar sensors is blocked by foreign material (such as
stickers or a bicycle carrier).
lThe radar sensors do not detect human, animal, shopping cart, bicycle, or static objects such as
fences.
lThe radar sensors may not detect all types of vehicles around your vehicle, especially the
following types of vehicles:
lMotorcycleslVehicles with body shapes that radar may not reflect such as a flatbed trailer with no cargo.lVehicles with lower body height such as sports cars.lAlthough the system may detect objects on the road side such as parked vehicles or guardrails and
operate the warning light/beep, it does not indicate a malfunction.
lIf the vehicle is driven on a road with less traffic and few vehicles that the radar sensors can
detect, the system may pause (the Blind Spot Monitoring (BSM) OFF indicator light in the
instrument panel flashes). However, it does not indicate a malfunction.
lThe following conditions may affect the visibility of the Blind Spot Monitoring (BSM) warning
lights on the outside mirror, making it difficult to confirm the illumination of the lights:
lIce or snow adheres to the surface of the outside mirrors.lThe door window glass is tinted.lThe radar sensors are equipped inside the rear bumper. (page 5-43)lHave the radar sensors inspected at an Authorized Mazda Dealer if any shock is applied to the
rear bumper, even in a minor accident. If the vehicle is driven with a damaged radar sensor, the
system may not operate properly resulting in an accident.
lFor repairs or paintwork around the radar sensors, or replacement of the bumper, consult an
Authorized Mazda Dealer.
lThe radar sensors of the Blind Spot Monitoring (BSM) system may be regulated under the radio
wave related laws of the country where the vehicle is driven. The sensors in this system are
approved for use in the U.S.A. (including territories), Canada, and Mexico. If a vehicle with a
Blind Spot Monitoring (BSM) system is driven in a country other than the U.S.A., Canada, or
Mexico, the system has to be turned off using the Blind Spot Monitoring (BSM) OFF switch.

qBlind Spot Monitoring (BSM)
The Blind Spot Monitoring (BSM) system monitors the detection areas on both sides of the
vehicle to the rear and when there are vehicles in the detection area it notifies the driver by
illuminating the Blind Spot Monitoring (BSM) warning light while the vehicle speed is
about 10 km/h (6.2 mph) or faster and driving forward.
If the turn signal lever is operated to the side the Blind Spot Monitoring (BSM) warning
light is illuminated, the Blind Spot Monitoring (BSM) warning light flashes and the system
warns the driver of the vehicle in the detection area using a BSM warning beep sound.

NOTElThe Blind Spot Monitoring (BSM) does not operate when the vehicle speed is lower than about 10
km/h (6.2 mph).
lThe detection area of the Blind Spot Monitoring (BSM) has been determined based on the lane
width of general freeways. Therefore on a road with a narrower lane width, the system may detect
vehicles on a lane next to the adjacent lane and operate the warning light/beep. On a road with
wider lane width, the system may not detect vehicles on the adjacent lane and may not operate the
warning light/beep.
lUnder the following conditions, the system may be unable to detect vehicles, or detection may be
delayed.
lThe vehicle accelerates from a standing-start with a vehicle alongside.lA vehicle moves from a lane two lanes over to the adjacent lane.lThe difference in vehicle speed between your vehicle and another vehicle is larger when
passing or being passed, and the vehicle passes the detection area within a short period of
time.
lOn a steep incline, or when there is a difference in height between lanes.lImmediately after the system has been activated by pressing the Blind Spot Monitoring (BSM)
OFF switch again after it has been turned off (Blind Spot Monitoring (BSM) OFF indicator
light in instrument panel illuminates) by pressing the switch.
lThe selector lever is shifted to the R position, or directly after being shifted from the R position.lThe system may not operate normally when towing a trailer. Turn off the system by operating the
Blind Spot Monitoring (BSM) OFF switch when towing a trailer.
lThe system switches to the Rear Cross Traffic Alert function when the selector lever is shifted to
the R position.
